SPECIFICATION forming part of Letters Patent No. 781,817, latecl February '7, 1905.

Application filed September 30,1904. Serial No. 226,641.

Io u/Z 11-71mm if many (Jo/merit:

Be it known that I, URI D. Fosrnn, a citizen of the United States, residing in Meriden, in the county of New Haven and State of Connecticut, have invented certainnew and useful Improvements in Batteries, of which the following is a specification.

This invention relates to batteries; and while such invention may be applied to batteries of various kinds it is especially directed in this instance to the so-called medical batteries.

It is an object of the present invention to provide an inexpensive, durable, and cflicient device.

It is a further object to provide antisplash instrumentalities, whereby it the battery is carried around the solution in the battery may not escape.

An embodiment of this invention is illustrated on the accompanyingsheet of drawings, whercon Figure 1 illustrates a sectional elevational view of a battery made in accordance with my invention, and Fig. 2 is a top plan view thereof.

Similar characters of reference indicate corresponding parts throughout the figures.

In the form shown I provide a battery having a lower enlarged portion 1 and an upper smaller portion 2, and at the intersection of said upper and lower portions in the present instance there is provided an inward-extending flange 3, which 1 will hereinafter designate as an antisplash flange or ring, and which extends sufliciently far inward to form an opening through which may pass a carbon at, which in the present instance, and preferably so, is in the form of a cylinder. This car-bon is provided with ahead 5, which rests on the seat 6, formed in a flange T in the mouth of the jar. The carbon 4: in the present instance is also provided with an extending ring or flange 8, which will also be hereinafter termed an antisplash flange or ring,

and this flange 8 is located on the outer wall of said carbon T and preferably at a point suitably distant above the antisplash flange or ring 3 carried by the jar.

\Yithin the carbon 4. is a zinc 9, which in the present instance may be provided with an extended flange 10, which will also be hereinafter designated as an antisplash-flange."

The upper mouth of the carbon i is provided with an annular opening 11, having a shoulder 12, in which is located a metal washer 13, having an opening la, in which is seated a non-conducting washer 15, through which is passed a screw-tln'eaded stem 16, which is preferably screw-tin'caded, as at 17, into the head 18 of the zinc 9, and interposed between said head 18 and a lower edge 19 of the mouth 11 of said carbon 4C is a washer or airproot'element 20, of any suitable non-conducting material, which element will keep the air from working in between the carbon & and the zinc 9. The head 18 of the zinc is also provided with a nozzle '21, having a channel 22, which extends down through said head 18 and communicates with the chamber of the carbon, and placed over said nozzle it is a tube 23, of any suitable material, and which is adapted to be used as a suction-tube for extracting the air within the sealed battery, whereby to create a vacuum and cause the height of the fluid indicated by the dotted line 2% to be siphoned to a height indicated by the dotted line It will be noticed that the carbon is provided with a vent 26, through which the fluid on the outside of the carbon may be siphoned until thesame falls in line with the bottomol' the vent.

For the purpose of holding the washers 13 and 15, respectively, in place I provide a nut 27, which is screw-threzuled into the post 16, and between said nut 27 and another nut, 28. may be secured a wire 29, a corresponding wire 30 being in the present instance suitably securedas, for instance, by solder ---to the washer 13, and said stem 16 may be further provided with an additional nut .28, above which is a rubber gasket 29, which may bear against the underside of a cover (not shown) of a suitable casing in which said battery or a plurality of them may be carried.

'ith respect to the flanges 3, 8, and 10, re-

spcctively, which have been hereiubefore designatcd as :intisplasli" flanges or rings, it

may be said that these are especially effective when the battery is being carried about for instance, as in a physicians carriage, provided the battery is used for medical purposes, when, as is obvious, they will prevent the upward splashing of the solution contained in the jar, which is a desideratum in batteries of this character.

It will be observed that by exhausting the air by a suction device the fluid may be brought up within the carbon around the Zinc to any desired height, whereupon the battery will becomeactive. When the exhaust force is removed, the fluid will rapidly descend and will run up outside the chamber, at which time the rings Sand 8 will prevent the splashing which would ordinarily occur, it being understood that during the period the battery is in action the antisplash-ring 10 will also serve the same purpose.

It will now be observed that I have provided an eiiicient, inexpensive, and durable structure and one adapted for various purposes and which is especially desirable as a medical battery.

W'ithout departing from the spirit of this invention 1 may resort to other constructions and modifications thereof.

Having thus described my invention, I claim- 1. In a battery the combination with ajar, a carbon located therein, a Zinc, antisplash devices located on said jar and carbon, and an antisplash device located on said Zinc.

2. In a battery the combination with a jar, of a carbon located therein, a zinc within the carbon, said jar, carbon and zinc each being provided with antisplash devices, the antisplash devices on the carbon and jar being projected in opposite directions.

3. In a battery, the combination with a jar having an upper portion and a lower enlarged portion, an antisplash-ring located at the intersection of said upper and lower portions, a carbon provided with an antisplash-ring on its outer wall and which is oppositely disposed to the ring aforementioned, a Zinc located in said carbon and provided with an antisplash-ring, and means for coupling said zinc and carbon together. 7

4. In a battery, the combination with a jar, of carbon located therein, a Zinc mounted in said carbon, an antisplash device between said jar and carbon; an antisplash device between said carbon and Zinc, an air-tight connection between said carbon and zinc, an air-inletting device carried by said Zinc, and a tube proceeding from said air-inletting device.

5. In a battery, the combination with a jar, a carbon and a zinc, an antisplash device between said jar and carbon; an antisplash device between said carbon and zinc, of a screwthreaded member secured to said zinc, a washer surrounding said screw-threaded member and mounted on said zinc, means for air-proofing the joint between said Zinc and carbon, and means to hold said washer in place.

6. In a battery, the combination with a jar, a carbon and a zinc, an antisplash device between said jar and carbon; an antisplash device between said carbon and Zinc, said zinc having an air suction orifice and an airproof element interposed between said Zinc and carbon.

7. A battery comprising a zinc, a carbon and a jar, an antisplash device between said jar and carbon; an antisplash device between said carbon and zinc, an air-tight connection between said zinc and carbon, said air-tight connection passing an air-proof element interposed between said carbon and zinc, a screwthreaded member, a washer held in place by said screw threaded member, and means mounted on said screw-threaded member by which a wire may be secured to the battery.

8. A battery comprising a jar having a lower portion enlarging from the upper portion, an antisplash-ring situated at the intersection of the upper and lower portion of said jar, a carbon whose outer wall is provided with an antisplash-ring disposed in a direction opposite to the first-mentioned splash-ring, a Zinc provided with a splash-ring, said Zinc being provided with a head-piece having an orifice, an elongated member screw-threaded into said head-piece, an air-proof element between said head-piece and the carbon, a washer located on said elongated element, and a nut for holding said washer in position whereby to form an air-proof joint.
